If the irrelevance is less than or equal to preset irrelevance threshold value, internal temperature prediction model parameters are not updated.
The calculating of irrelevance can be missed using mean absolute error, average absolute percentage error, root mean square in the present embodiment
One of difference, related coefficient, coefficient of determination calculate, and using a variety of while calculating and can also count by weighted summation
Final irrelevance.
(3) temperature prediction
Internal temperature prediction model based on t moment predicts the t+1 moment according to the second data set that the moment obtains
Temperature value y (t+1), is shown below.
Y (t+1)=f (x (t), x (t-1) ..., x (t-d+1), y (t), y (t-1) ..., y (t-d+1))
Wherein, f () is the anticipation function of internal temperature prediction model.
Step S40 generates the control signal of vehicles electrochomeric glass transparency, and foundation according to the estimated value
The signal adjusts electrochomeric glass transparency.
The thinking of the step is to be converted to obtain a certain index request according to the temperature value of prediction result, when the index request
When more than a certain range, thus provide electrochomeric glass correspond to the control signal of state of a control with change its control electric current it is big
It is small.
The method that the present embodiment generates control signal specifically:
The estimated value is become the corresponding index value of estimated value according to preset transformation rule by step S401.
In the step, transformation rule can be the mapping relations of vehicle interior temperature and human thermal comfort degree.Human thermal comfort degree
It can be formulated based on bayesian scale, ASHRAE scale, iso standard or other index requests being widely recognized as, Ke Yitong
Cross Body Comfort Index expression.
Step S402, it is saturating based on preset control rules vehicles electrochomeric glass according to the index value
The control signal of lightness.
In the step, control rule is the mapping of Studies of Human Body Heat comfort level and the adjustment of vehicles electrochomeric glass transparency
Relationship.
For example, 7 grades of thermal comfort index of ASHRAE scale be it is cold, cool, micro- cool, neutral, micro- warm, warm, hot, when according to prediction knot
When the Temperature numerical calculation thermal comfort of fruit refers to as heat, provides electrochomeric glass state of a control and reach coloured state；When according to prediction
As a result Temperature numerical calculation thermal comfort refers to when being cold, provides electrochomeric glass state of a control and reaches transparent state.For another example
Iso standard human thermal comfort evaluation index is according to physical activity degree, clothes thermal resistance (clothing situation), air themperature, air
What 6 factors such as humidity, mean radiant temperature, speed air flow determined, in addition to air themperature index is by being arranged in traffic
Other than air temperature sensor in tool measures, other parameters can by rule of thumb or documents and materials inquiry takes estimated value.
